Hey anjali,

you have a lot of time for the logical reasoning and aptitude syllabus of the exam. It can be completed within 6 to 8 months. But you should start focusing on the GK part and start preparing for it as soon as possible. The more time you give to GK and current affairs the more chances you will have of clearing the exam. Also start preparing for the rest of the syllabus in the 2nd or 3rd year of college.

All the best!!
